Puerto Rican artist Alexis Diaz (previously) brings textures and patterns reminiscent of traditional engraving techniques to his murals of phantasmagorical creatures using only a paintbrush. Twisting tentacles, strange fusions of anatomy, beings wrapped in plants, all rendered atop colorful gradients create an unmistakable style Diaz has become famous for. You can see much more of his work here. (via Cross Connect)
